Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.

What is the total displacement of the car after 5 h? Question 4 options: 0 km 15 km 20 km 40km.
Likurg_2 [28]

Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.

Displacement:

It is a vector quantity that is defined as the overall change in the position of the object.

The formula for displacement is:

s = s_f-s_i

Where,

s - total displacement

s_f - final position

s_i- initial position

In the given graph:

  • Car displaces 15 km in 2 hrs
  • Car displaces 20 km in 4 hrs.
  • The car moves back to the initial position in 5 hrs.

Therefore, the displacement of the car in 5 hrs is 0 km.
